jerks are not worth the extra time and effort - here's why

I have friends (usually guys) who would offer wise words such as "If you like him, you have to show it! Don't be afraid to make the first move to chat him up..."

I'm sure there were other gems but they're archived at the back of my mind - Area R.
R for redundant, R for ridiculous.

I'm fully entitled to my opinion just as you are entitled to yours. In no way, am I hating on men.

Guys like girls to put in that bit more effort. I'm saying, girls shouldn't.
WHY?

First things first, the guy in question matters. His character, his mentality when it comes to these things.
If he's one of those nice guys who are truly appreciative of your efforts, go ahead and invest your time. I'm not saying you shouldn't.

However, if he's the type whom you know/suspect has many girls on his roster and would very likely get an inflated ego, don't feed his self-importance.
What a douche! You're better off without him.

With these guys, there's a hierarchical pyramid where they sort their girl friends.
At the top you have the girls whom they are interested in but are not showing interest in them. Such guys typically fancy a challenge so these are the girls whom they are most likely trying to impress and working very hard on getting to know.

In the middle are the girls whom are in 'friend' territory and are above average-looking. They're the ones these guys look to when they need company; someone they can show off in public proudly. Something like arm trophy and as a bonus, not uncomfortable to hang out with.

At the bottom, there are 2 classes. On one side, you have the friends who are not very chio or not chio at all. He's probably never going to be interested in them.
On the other side, these are the girls who like him way more than he likes them. Because of that, he knows they are always there and are like some sort of back-up plan. He might or might not have interest in them.

SO, if you're going to put in extra effort for a guy who is such a jerk, you end up at the base of the pyramid. Which is not a good place to be!
While I'm typing this, I feel sorry for girls in that position because you have no backbone! You're letting a guy step all over you!

In conclusion, I don't advocate aggressive pursuit of any guy. If he likes you, I'm sure he can read the hints you're dropping (yes, at least drop some hints and not put on a black face) and make a move.
If not, he's not the one for you.
